2 Claims. (Cl. 2-14) This invention relates to adjustable head bands for goggles, respirators and the like.

Goggles and thelike have heretofore been provided with head bands having adjusting'provisions thereon for fitting the assembly to the head of the wearer but such head band adjusting provisions have been cumbersome and difiioult to adjust.

The. prinoipal object of this invention is to provide an improved adjustable head band which is not cumbersome, which may be readily adjusted, which is inexpensive and which adds to the comfort of the wearer.

.In this respect goggles and the like are usually provided with head band securing holes and the adjustable head band of this invention may readily be applied to such securing holes. The head band' consistsof a strip of resilient and extensible material, such" as rubber, rubber composition or like material to be received in the securing holes of the goggles and the like. The strip of resilient and extensible material has a normal cross sectional area greater than the securing holes so that the strip is frictionally held in place in the securing holes. When the strip is extended a substantial amount, the cross sectional area thereof decreases which permits adjustable positioning of the strip in the securing holes. k v I The resilient and extensible strip may also be provided with a plurality of spacedflanges which are also normally of cross sectional area greater than the securing holes to assist in securing the strip in place in the securing-holes. Extension of the strip also reduces the cross sectional area of the flanges to permit them tobe pulled through the securing holes for adjustment purposes In-goggles and the like wherein the securing holes are provided with reduced entry slots, extension of the strip will reduce the cross sectional area of the strip sufficiently to permit insertion and removal of the strip through the reduced entry slots for adjustment purposes. The strip may also be provided with tapered ends to facilitate the insertion of the strip into the securing holes.

The strip is preferably of round cross section so that when the goggles or the like are put on or taken off by the wearer, the head band may roll upon the back of the head of the wearer,

thereby greatly facilitating the putting on and taking ofi of the goggles and the like.

Other objects and advantages will become apparent to those skilled in the art upon reference to the accompanying specification, claimsand drawing, in which-- i Fig. 1 is a perspective view of a pair of goggles with the head band of this invention applied thereto;

Fig. 2 is an enlarged sectional view through the goggles where the head band is secured thereto;

Fig. 3 is a view similar to Fig. 2, showing the head band substantially elongated;

Fig. fl is a sectional view similar to Fig. 2

but showing a modified construction;

Fig. 5 is a perspective view of a portion of a modified form of goggles; and

Fig. 6 is an enlarged sectional view showing the manner of attaching the head band to the goggle arrangementof Fig. 5.

While the head band of thisinvention may be applied to goggles, respirators and similar devices, it is disclosed for purposes of illustration as being applied to a pair of goggles generally designated at In in Fig. 1.

The goggles may include lenses II held in place in lens boxes I2 provided with ventilated side shields I3 and a bridge I4 between the lens boxes I2. The head band of this invention is designated I5 and may be formed of rubber, rubber composition or similar material which is resilient and extensible.

Referring to Fig. 2, the lens box I2 of the gogg es is provided with a flange II having a head band securing hole I8 therein for receiving and securing the resilient and extensible head band I5. The head band I5 has its ends tapered as at I6 to facilitate insertion of said head band into the securing holes I8 of the goggles. The resilient and extensible strip I5 forming the head band preferably has a normal cross sectional area greater than that of the securing holes I8 so that the head band I5 is frictionally held in place in the securing holes I8. Also, the head band I5 is preferably provided with a plurality of spaced flanges l9 formed integrally with the head band I5 and which also have a cross sectional area greater than that of the securing holes I 8. The spaced flanges cooperate with the flange I! of the goggles to prevent slippage of the head band I5 longitudinally through the securing holes l8 while the goggles and head band are applied to the head of the wearer.

In order to adjust the eifective length of the head band I5 all that is necessary is to'extend the head band I5 adjacent the securing holes I8 as by oppositely pulling on the head band on either side of the flange II. As a result the extensible and resilient strip [5 of the head band will be reduced in cross sectional area so as to free the strip from the securing holes l8 and will also reduce somewhat the cross sectional area of the flange [9 as is illustrated in Fig. 3. Because of this reduction in cross sectional area of the component parts of the head band 15, the head band may be longitudinally shifted through the securing hole is to a new position. In this way adjustment of the effective length of the head band 15 may be readily accomplished merely by Stretching the head band [5 at the securing holes l8 and then longitudinally sliding the head band l5 and its flanges [9 through the securing holes l8 to the desired adjusted position.

In the arrangement of Fig. 4, the goggle portion [2 may be provided With an eyelet 2| for receiving the extensible and flexible strip l5 forming the head band, Here, however, the flanges 19 are shown to be eliminated so that the securing of the head band IS in place within the eyelets 2| is obtained solely by the gripping of the head band l5 within the eyelets 2 I The head band may be longitudinally adjusted by stretching the same adjacent the eyelets 2| to reduce the cross sectional area of the head band 55 sufficiently to permit longitudinal shifting thereof within the eyelets 2! to the desired adjusted position. As in the previous modification the ends of the head band [5 are tapered at it to facilitate insertion of the head band l5 within the eyelets 2i.

A modified arrangement of the invention is shown in Figs. 5 and 6. The ventilated side shields 13 are provided with a flange 23 having a head band securing hole 24 and a reduced entry slot 25. The head band i5 is in all respects the same as that of the modification illustrated in Figs. 1 to 3. In order to insert the head band I5 in the securing hole 24 it is stretched to reduce the cross sectional area thereof sufficiently to permit insertion thereof through 'the reduced entry slot 25 into the securing hole 24, When the stretching action is relieved the cross sectional area of the head band [3 will increase sufiiciently to retain the head band IS in the securing hole 24 and prevent sliding of the head band out through the reduced entry slot 25. The flanges I9 on the head band [5 prevent slippage of the head band l5 longitudinally through the securing hole 24 as in the previous modification.

In order to adjust the eifective length of the head band 15 it may be stretched adjacent the securing hole 24 to reduce the cross sectional area thereof sufiiciently to permit withdrawal through the reduced entry slot 25 and then the head band maybe reinserted in the above manner into the securing hole 24 at the desired place on the head band.

Preferably the head band I5 is round in cross section so that when the head band is applied to the head of the wearer it may roll on the back of the head, thereby greatly facilitating the applition of the assembly to the head of the wearer and adding greatly to the comfort of the wearer.

While for purposes of illustration several forms of this invention have been disclosed, other forms thereof may become apparent to those skilled in the art and, therefore, this invention is to be limited only by the scope of the appended claims and prior art.

I claim as my invention:

1. An adjustable head band for goggles and the like having securing holes at opposite sides thereof comprising a resilient and extensible strip of rubber or the like of substantially roundcross section to be received in the securing holes and having adjacent each end a plurality of integral spaced apart annular flanges having a normal cross sectional area greater than the securing holes for firmly retaining the ends of the strip in adjusted position in the securing holes, the cross sectional area of the resilient and extensible strip and flanges thereof bein appreciably reduced upon forceful extension of the strip to permit pulling of the flanges through the securing holes for providing longitudinal adjustable positioning of the ends of the strip in the securing holes.

2. An adjustable head band for goggles and the like having securing holes at opposite sides thereof comprising a resilient and extensible strip of rubber or the like of substantially round cross section to be received in the securing holes and having adjacent each end a plurality of integral spaced apart annular flanges having a normal cross sectional area greater than the securing holes for firmly retaining the ends of the strip in adjusted position in the securing holes, the cross sectional area of the resilient and extensible strip and flanges thereof being appreciably reduced upon forceful extension of the strip to permit pulling of the flanges through the securing holes for providin longitudinal adjustable positioning of the ends of the strip in the securing holes, and having integral tapered extensions on the ends of the strip to facilitate insertion of the ends of the strip in the securing holes.
